You’re looking at a rare physical artifact from the twilight of shareware’s golden age.

Way back in 1996, when Gears of War maker Epic Games still went by “Epic MegaGames,” I ordered a few registered copies of its shareware games through CompuServe.

Since it was a special buy-and-download deal (very unusual in 1996), I didn’t receive copies of the games themselves on disk. Instead, Epic mailed an invoice, copies of the games’ instruction manuals (which have been displaced from this set, or else I would have scanned them too) and a shareware demo disk from Epic partner Safari Software.

You’ve probably heard of Epic Games by now — you know, the company behind Gears of War and the Unreal Engine. We read a lot about those blockbuster products these days, but Epic’s story stretches back much farther than that. For example, did you know that the very same Epic was once one of the world’s foremost shareware game publishers?

In January of this year, I had the immense honor of exploring Epic’s rich history in a sit-down interview with Tim Sweeney, founder and CEO of Epic. Over lunch at a local restaurant, we discussed his early programming years, the genesis of ZZT (Epic’s first game), Jill of the Jungle, Apogee Software, the shareware wars, his thoughts on id Software’s early work, the future of game graphics, and much more.

After some time on the back burner, this long, in-depth interview has finally seen the light of day over at Gamasutra. Shareware fans and general history computer buffs shouldn’t miss it. Heck, I did the interview and I’m reading it again. I hope you enjoy it.

Read any popular game publication these days, and you’ll probably come across ample mention of Epic Games’ Unreal Engine, the 3D powerhouse behind blockbuster first-person shooters like Bioshock and Gears of War. Believe it or not, one of today’s hottest game engines traces its roots back to a 2D text-based game programmed by a University of Maryland college student during the golden age of shareware.

Tim Sweeney founded Potomac Computer Systems in 1991 with the release of ZZT, a graphical ASCII character-based game that ran on a simple object-oriented platform programmed by Sweeney. With an in-game editor, Sweeney created multiple ZZT episodes that he sold to finance the new company. Luckily, Sweeney didn’t limit the in-game editor to himself; it featured prominently on the title screen of the free shareware edition. Much to Sweeney’s surprise, the editor itself soon became the most popular part of ZZT, allowing players to create their own games in the ZZT engine. Potomac changed its name to Epic MegaGames, and a shareware giant was born.

A large community of rabid ZZT fans still thrives thanks to the Internet, where enthusiasts trade nostalgia, user-made games, and the latest attempts to squeeze every last drop out of the ZZT engine through emergent programming techniques. For example, clever world builders have managed to reproduce just about every major 2D game genre — even genres the engine wasn’t designed for — in ZZT‘s editor, albeit in primitive forms. For modern ZZT fans, the game’s fun lies not only in playing the community’s user-created games, but in the challenge of creating new and unexpected things with a simple set of tools and components.

The original shareware package of ZZT only included one game: Town of ZZT, a whimsical adventure created by Sweeney that calls upon a player’s action and puzzle-solving skills. But in the late 1990s, Epic released all of Sweeney’s classic ZZT episodes as freeware, so you’ll find those worlds in the file below as well, including Dungeons of ZZT.

Includes full Town, City, Caves, and Dungeons of ZZT episodes. ZZT runs pretty well on modern computers under Windows. You might also want to try running the game under DOSBox. Uses the PC speaker for sound.
